TEHRAN, Aug. 26 (Xinhua) -- UN Under-Secretary-General for Political Affairs Jeffrey Feltman is scheduled to visit Iran later in the day to discuss the latest developments in the Middle East, including Syria, Tehran Times daily reported on Monday.
According to the report, Feltman, a former U.S. diplomat, will hold a meeting with Iranian Foreign Minister Mohammad-Javad Zarif to discuss developments in Syria, Egypt, and Lebanon.
He had visited Iran accompanying UN chief Ban Ki-moon to the Non-Aligned Movement summit in Tehran, in August 2012.
Feltman recently visited a number of other countries in the Middle East, including Egypt. He arrived in Cairo on Aug. 20 for talks with Egyptian officials on the country's current state of unrest.
On Sunday, Iran's armed forces Deputy Chief of Staff, General Masoud Jazayeri, warned that crossing "red line" on Syria will have dire consequences.
"The United States is clear about the Syria red line and any transgress of Syria red line will have dire consequences for the United States," said Jazayeri in an allusion to the recent statements of the U.S. commanders about possible military intervention in Syria over the alleged involvement of Syrian government in the recent chemical attack on civilians.
Iran is a main ally of the Syrian government in the region and has backed the Lebanese Shiite Hezbollah group to fight on the side of governmental forces against Syrian rebels, which it considers as "terrorist groups."
